On my esp32 project, I use Preferences.h to store some values over rebooting.

I have the issue that mypref.begin("nameSpc", false); returns 0 in one case, but works in a other part of the program.

So I'm looking for debugging and found some things like ESP_LOGI ESP_LOGE.

How I use this mechanic agains Preferences.h / mypref.begin()?

I don't understand this and have not found any examples that take me to AHA!

oh, my goodness...

it's easier as it's look's. To have some debugging output over Serial you must: Tools->Core Debug Level -> verbose and

#if (!PLATFORMIO)
  // Enable Arduino-ESP32 logging in Arduino IDE
  #ifdef CORE_DEBUG_LEVEL
    #undef CORE_DEBUG_LEVEL
  #endif
  #ifdef LOG_LOCAL_LEVEL
    #undef LOG_LOCAL_LEVEL
  #endif

#define CORE_DEBUG_LEVEL 4
  #define LOG_LOCAL_LEVEL CORE_DEBUG_LEVEL
#endif


#include <esp32-hal-log.h>

Thats all, now i've got what i' looking for ;-) Can be closed!
